HYIbROOARBON GAS 'rImnINE.

To all whom it may concern:

Be it known that I, Isaac N. REED, a citizen of the United States,residing at Jersey City, in the county of Hudson and State of NewJersey, have invented new and useful Improvements in Hydrocarbon GasTurbines, of which the following is a specification.

This invention relates toa rotary engine or turbine of that type inwhich'the motive fluid consists of an exploded charge of carburetedhydro-carbon. l

The invention has for one of its objects to improve and simplify theconstruction and operation of prime movers of this character so as to becomparatively slmple and inexpensive to manufacture, reliable andefficient in use, and composed of comparatively few parts.

Another object of the invention is the provision of a novel arran ementof rotary sta tionhry buckets and ischarge nozzles, in combination withmeans for producing a motive fluid "of high pressure to be dischargedthrough the nozzles to the buckets'f With these objects in view andothers, as-

will appear as the description proceeds,'the invention. comprises thevarious novel features of construction and arrangement of parts whichwill be more fully described hereinafter and set forth withparticularity in the claims appended hereto. Inthe accom anyingdrawings, which iiodiment of the invention,

Figure 1 is an end view of the machine.

Fig. 2 is a vertical section taken trans versely to the axis ofrotation. Fig. 3 is a vertical section on line 33, Fig. 2. Fig. 4 is aplan view. Fig. 5 is a detail sectional view of the nozzles showingtheir relation to the buckets.

Similar reference characters are employed to designate correspondingparts throughout the views.

Referring to the drawings, A designates the turbine, and B, thefluid-producing device mounted on the turbine and operatively relatedthereto 'so that the nozzles will re" ceive motive fluid at highressure.

The turbine A consists o a casing 1 of any approved construction, throuh which passes a central shaft, the shaft being journaled in bearings 3at the heads 4; of the casing. Arran ed in the casing and mounted onthe'shaft 1s a wheel of the double axial Specification of LettersPatent.

flow t pe, said wheel consisting of two sets "of dis .s 'r and Zlocated, respectively, to the right and left of, the central transverseplane of the casing, there being shown two disks in each set, but it isto be understoodthat any desired number of bucket-carrying elements ordisks may be provided/ On the periphery of each disk are radial buckets5 of proper curvature, and between adjacent rotating rows of buckets arestationary intermediate buckets 6 that are curved oppositely to thewheel or moving buckets so as to reverse the direction of fiow of themotive fluid in its passage from one set of moving buckets to the nextadjacent set. The casing is provided with an internal projection or web7 that is located in the ccntral-transverse lane and disposed betweenthe inner mcst' iskson the shaft 2, and in this Web areoppositely-inclined discharging devices or nozzles 8 that are disposedatthe proper angle with respect to the wheel buckets, the said nozzlesbeing connected with the common throat or passage 9 through which the;

motive fluid or exploded gases pass to the nozzles. The exploded fluidis discharged intermittently, and being 'ofhi'gh temperature, it isdesirable to increase the volume.

of the motive fluid by discharging water or other fluid into the throat9 at the time the fired gases pass therethrough, and for this urpose aconduit or passage 10 is formed in the wall'of the casing to lead intothe throatQ, the said conduit being connected with a suitable device(not shown) for discharging'a definite amount of water at the properinterval.

" The fluid-producing device B consists of a 'cylinder'll mounted on thecasing or 10- cat'ed in any other suitable point, and in this cylinder'reciprocates a compression piston 12 that is connected with the pitman13- which is operated by an eccentric 14, said eccentric being arrangedon a shaft 15 that has a wheel 16 connected by a belt or sprocket chain17 with a wheel or sprocket 18 on the main shaft 2. The eccentric shaftis jou-rnaled in bearings 19.formed on the turbine casing, and on thisshaft is a hand wheel-20 whereby the eccentric shaft can be turned foroperating the compressor or pump piston 12. The cylinder connected by apipe '21 with a carburetor or other source of explosive mixture so thatwhen the piston moves forwardly, a charge will be Patented Mar. 26,1912.

l cation is interrupted b y the piston or {01- drawn into the cylinderand subsequently com ressed on the inward or rear stroke.

In t ahead 22 of the cylinder isYormed an explosion chamber 23that isconnected with the cylinderthrough a port orpassa e 24, the said passagebeing normally close by a puppet valve 25 which has a stem 26 passingoutwardly through a plug 27, there being a spring 28 on the other end ofthe stem that operates to automatically close the valve between thecylinder and combustion chamadapted to communicate with the throat. ofthe nozzles immediately after-"the dompressed explosive charge in thechamber 23 1s ignited, but at other times the communilower 29 that movesacross thechainber 23 and engages the seat 30 at the receiving end' ofthe nozzle throat 9.' The'piston valve'29 I'm provided with a stem 31which is con- 'nected at 32, with a lever or rocker 33, the

. latter being fulcrumed at 34 in a bearing 35 "on the head of thecylinder. Att'he.head

{at the cylinder is a transverseshaft 26 mounted in bearings 37,andon'this shaft shaft 1 5 'is a cam 38 that wipes on the lever 33 in-such'a manner that the piston valve 29"is moved to open position atthe' properin.-

valve 29 being closed at'this t-iiii The gases in the chamber 23 are nowignited by a spark plug Mo -equivalent device, and the valve 29 opens topermit theexploded gases tov pass. 'to' the turbine," the force ofexplosion insuring the closing of thavalve 425. While the exploded gasespassthrough.

the nozzle, is'injected into magm so as vto be converted into stezjuntoinc'rease thevolume of the rii'otive 'fluid., ,Whi1e,'thefm o-; tivefluid, is discharging to the turbine, the

piston 12 moves outwardlyi flto draw .in

another charge ofmixture so that thecycle This combustion chamber 23'just described will be repeated and in this way continuous rotation ofthe turbine Wheel maintained. f.

From the foregoing description, taken in connection with theaccompanying drawings, the advantages of the construction and of themethod of operation will be readily apparent to those skilled inthe artto which the invention appertains, and while I have describedtheprinciple of operation of the invention, together with the apparatuswhich I now consider to be the best embodiment thereof, I desire to haveit understood that the apparatus shown is merely illustrative, and thatsuch changes may be made claims appended hereto.

, Having thus described the invention, what I claim as new, is

1. The combination of a turbine including sets of revolving buckets, andoppositely discharging nozzles dis oscd between the said sets fordelivering aid to both simultaneously, said nozzles having a commonthroat, with a combustion chamber adjacent the "said throat, a. valvefor closing the when desired as are within the scope of the I throat forinterrupting communication betfweenfthe' chamber and nozzles, meansfordelivering a compressed charge of explosive mixture to the chamber,means for guiding the-mixture in the chamben'and means for the ignitionof the harge'. '2. The combination of a turbine includingsets'ofrevol'ving buckets, and oppositely discharging nozzles disposedbetween the opening-the saidhvalve ,in-. timed relation to a said setsfor delivering fluid to both simultaneo'usly', said nozzles having acommon throat, with a combustion chamber adjacent the said throat, avalve for closing the throat for interrupting communication between'thechamber and nozzles, means for delivering-a compressed charge ofexplosive .mixtureto the chamber, means for vguiding the mixture in thechamber, means for opening the said valve in" timed relationtg theignition of the charge, and means through which liquid is delivered tothe throat/of the nozzles simultaneously ,-.with the passage of thefired gases therethrough.
